CONVERTIBLE WRENCH AND VISE.

SPECIFICATION forming part of Letters vPatent N0."770,058, datedSeptember 13, 1904. Appliction led July 29,1903. Serial No. 167,425. (Nomodel.)

T0 all wiz/0711. it may concern/.-

Be it known that I, WILLIAM PHILLIPS Fos- TER, a citizen of the UnitedStates, and a resident of Jacumba Springs, (Campo P.O. in the county ofSan Diego and State of California, have invented a new and ImprovedConvertible Wrench and Vise, of which the following is a full, clear,and exactdescription.

This invention has for its object to provide novel details ofconstruction for a wrench of the adjustable-jaw type which enables thequick and convenient conversion of the wrench into a vise either formanual use or as a fixture upon a stable support and also permits theexchange of parts of the implement to again convert it into asliding-jaw wrench, as occasion may require.

The invention consists in the novel construction and combination ofparts, as is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a partly-sectional perspective view of the implementarranged as a slidingjaw wrench. Fig. 2 is a partly-sectional side viewof the combination-tool adjusted to provide a hand-vise adapted to holdwork conveniently and permit it to be manually supported. Fig. 3 is aperspective view of the improvement arranged to serve as a stationaryvise. Fig. 4 is a transverse sectional view substantially on the line 44 in Fig. 3. Fig. 5 is a perspective view of a bracket-plate employedfor converting the implement from a hand-vise'into a stationary vise,and Fig. 6 is a perspective view in part of a lever-bar employed.

The sliding-jaw wrench is mainly of the usual construction andessentially comprises the following details.

rI he lever-bar 10 is provided with a fixed jaw 11 at one end and anattachable handle 12 at the opposite end, said handle havingl ashouldered screw 12, extended centrally from one end thereof and screwedinto a threaded longitudinal perforation 12C, centrally formed in theend of the lever-bar, whereon the handle is thus removably secured.

A sliding jaw 14 is loosely mounted -upon the lever-bar IO and is heldfor adjustment toward and from the fixed jaw 11 bya screw 15, thatloosely engages a perforated boss 10, formed or secured on the lever 10near the abutmentear 12b, formed on the handle 12, and whereon themilled head 15u of the screw 15 loosely bears when the handle is securedupon the lever-bar, as is clearly shown in Fig. 1. It will be seen thatthe head 15 of the screw 15 is loosely held between the boss 10XL andear 12b, so that the rotation of the head will move the sliding jaw 14toward or from the fixed jaw 11, as is usual in this type of wrenches.

To conduce to the proper action of the more important details of thewrench, itis preferred to employ the following coacting means: Akeeper-bolt 16 is held to slide in the head of the handle 12 and has aloose engagement within a longitudinal perforation opposite a simi- -larperforation a in the adjacent end of the lever-bar, a lateral projectiona on the keeperbolt affording means for its manipulation to effect aninterlocking insertion of one end of the bolt 16 within the perforationin the lever-bar, which will obviously hold the handle from turningwhile in use.

In the heel portion 11 of the fixed jaw 11 a central .longitudinalperforation is formed, which is threaded in its side wall for thereception of the shouldered screw 12, which when fully inserted thereinserves to detachably secure the handle 12 on the fixed jaw andsubstantially alined therewith. A suitable perforation is formed at aproper point in the heel of the fixed jaw 11 for the reception of thelocking end of the keeper-bolt 16', which when engaged within saidperforation will kprevent the slightest turning movement of the screw12, thus rendering the handle a rigid fixture on the jaw from which itprojects.

The milled head 15 on the adjusting-screw 15 is transversely perforated,as shown at b, and in this perforation a lever-bar 18 is looselyinserted when the implement is arranged for service as a hand-vise, saidlever having a fixed head c on one end and a removable head c on theopposite end, which latter when detached permits the lever to freelypass through the head 15, the replac- IOO ing of said. head o serving tohold the lever therein for use when the jaw 14 is to be adjusted towardor from the fixed jaw 11, thus providing a hand-vise wherein objects ofdifferent dimensions may be grasped and held, as is usual in the use ofsuch tools.

As a convenient and preferred means for converting the hand-vise into avise capable of being readily afxed upon y a stationary bunch or thelike for holding work a bracketplate 19 is provided. As shown in Fig. 5,the plate 19 consists of a flat piece of metal having an open slot eformed therein and extending from one edge inwardly, the side edges e ofthe slot being parallel with each other and spaced apart a distanceequal to the thickness of the iixed jaw 11 between the bottom surfacesof the recesses or channels d, so that these side edges of thebracket-plate may be slid into the channels d, that are formed in thesides ofthe fixed jaws 11 and eect a detachable connection of thebracket-plate with said iixed jaw, as is clearly shown in Figs. 3 and 4,this engagement being effected after the handle 12 is removed. Asuitable number of screw-holes g is formed in the bracket-plate 19 belowthe slot e therein, and from the relative position of the plate on thejaw 11 said jaw may be held fixed Vupon the work-bench A by screws 20,inserted into the edge of the bench through the screw-holes g.

It will be seen that the attachment .of the bracket-plate 19, asdescribed, and its connection with the fixed jaw 11 will project theportion 10 horizontally away from the bench A, thus disposing the jaw 14upright and permitting it to ser-ve as the adjustable jaw of astationary vise, the lever 18 and screw 15 affording means for a slidingmovement .of the jaw 14, as may be desired. It is obvious that by aremoval of the lever 18 from the milled and perforated headvl and thebracket-plate 19 from the fixed jaw 11 the engagement of the screwextension 12L withinthe perforation in the lever-bar 10 will convert theimplement into a sliding-jaw wrench.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a convertible wrench or vise, the combinationwith a lever-bar, and a fixed jaw on one end of the lever-bar, said jawhaving a longitudinal threaded perforation extending from its heel end,of a handle having a screw projected centrally from one end thereof andadapted to screw into the perforation in the fixed jaw, thus disposingthe lever-bar at one side of the handle and at a right angle thereto.

2. In a convertible wrench and vise, the combination with a lever-bar, afixed jaw on one end of said bar, having a longitudinal central threadedperforation therein extended from its lower end, a slidable jaw on saidbar, an adjusting-screw engaging the slidable jaw and held to rotate onthe lever-bar, and a lever engaging a perforated head on theadjusting-screw, yof a handle hav-ing a projecting screw on one endthereof, adapted to engage the longitudinal threaded perforation in thefixed jaw, thus disposing the lever-bar at a right angle to the axis ofthe handle, and means for holding the handle from unscrewing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM PHILLIPS FOSTER.
